Nelson Campelo currently Head of Atos South America would assume the role of CEO of Semantix while Leonardo Santos Poça D’água, Semantix’s founder and current CEO would become the Executive Chairman of the Group, focusing on the company's long-term strategy and innovation.

By joining forces with Semantix, a leader in data and artificial intelligence, we are entering in a new phase of expansion with enhanced capabilities to create even more value for clients, partners, employees and society."
